Technical note

CUB to IGS: what to expect from the conversion

Geospatial coordinates are absolute positions on the earth, and they are large: a projected easting runs to six or seven digits, while latitude and longitude are small decimals. IGS expects a drawing laid out near its own origin in millimetres or inches. The geometry itself converts correctly, but it can land tens of kilometres from 0,0, or arrive at a scale where an entire county is forty units across. Zoom to extents first, then measure one known distance before dimensioning anything. A CUB file has a pixel count and a DPI value, and no real-world size at all. IGS is a drawing where one unit means one millimetre or one inch, so the conversion has to assign a scale. Set the DPI before the run rather than resizing afterwards, then measure one feature of known length in the output and scale the drawing once to match it. Everything downstream, from dimensioning to cutting, rests on that single check.

Map Data Workflow

From map data to a working drawing

Site plans, utility routes and parcel boundaries often start out as CUB and end up in IGS. reaConverter turns the layers into drawing entities in batch, so a full project folder moves across in one run.

  • Convert every layer in a folder to IGS with the same settings
  • Go the other way too, from DWG to Shapefile, when the GIS team needs the drawings back
  • Render the same data to PDF for a quick review copy
  • Pick up new data automatically with Watch Folders, or script the job from the command line

Everything runs on your PC, which matters for cadastral, utility and client data that should not pass through an upload form.

FAQ

CUB to IGS Conversion

What are CUB files?

CUB is the cube file format of the Integrated Software for Imagers and Spectrometers (ISIS), developed by the USGS Astrogeology Science Center to process planetary imagery and spectral data returned by space missions. A file of this type stores a three-dimensional array of pixels defined by samples, lines, and bands, together with a text label written in Planetary Data System Version 3 (PDS3) keyword syntax. The label describes the dimensions, pixel type, byte order, target body, map projection, and instrument and acquisition details, and may be followed by additional objects such as history records, camera geometry tables, and polygon footprints. The label can be attached at the beginning of the file or stored in a separate file. The format is used for mosaics, map-projected images, and elevation models of the Moon, Mars, and other solar system bodies.

What are IGS files?

The IGS (Initial Graphics Exchange Specification) file format is a standardized CAD data exchange format used to transfer 2D and 3D model data between different CAD systems. Developed in the 1980s, IGES ensures compatibility across various engineering and design software by storing geometric data, annotations, and structure in a neutral ASCII or binary format.
